Re: installation issue

Mitesh, I agree with Sanju. Unless you have a very good reason for wanting the older version I suggest you use the latest released version. There are many reasons in addition to what Sanju said to use the latest version:

1) Java. Protege require Java to work. Those older versions were tested with older versions of Java. There is no guarantee they will work correctly with the current version of Java and you don't want to revert back to an older version of Java because that may cause issues for other programs on your device that use Java as well as possibly opening security holes that were patched in the old versions.

2) Reasoners. Protege without a Reasoner is a far less useful tool. The reasoners are (at least as far as I know) developed independently from Protege. They too are regularly updated to use the latest version of Java so you would need to find an older version of a Reasoner. And the same for all the other plugins.

3) Support. I think almost all the experienced Protege users who reply on this list are using either the current version or the beta version. If you have a question or problem with version 4.3 it will be difficult or impossible for us to replicate it or to give you much help.

The current version of Protege can be found here: https://protege.stanford.edu/ There is a big red box that says "Download Now" That will take you to the appropriate page (based on whether you are on a Mac, Windows, or Linux) with the latest download which I think if 5.2. BTW, there is also a beta version available. If you are a new user I would recommend installing the latest tested version not the beta.
